NOISY FISH.
M. Cuvier lately read a short paper to the French academy on the species of fish called pogonias, in which he particularly adverted to the noise by which they make themselves heard, even under water. However difficult the explanation of this phenomenon, there can be no doubt of its existence; the evidence of it adduced by M. Cuvier being perfectly satisfactory. The silurus, a large and ravenous fish, which abounds in the Danube, gives daily proof of it.
